Warmth, Clarity, and Character in a Small-diaphragm Tube Condenser

Sweetwater is excited to present you with another valuable tool in your quest to make better-sounding recordings. Handcrafted in Russia, the Soyuz 013 Tube small-diaphragm condenser microphone combines audio precision and transformer color to deliver impressive musicality and versatility. With its smooth, round top end and ability to capture precise detail, the 013 Tube is ideal for drum overheads as well as acoustic guitar, piano, choral ensembles, strings, orchestras, or any musical setting where warmth, clarity, and character are paramount.

Well-rounded performer

The Soyuz 013 Tube combines the best qualities of coveted small-diaphragm condenser designs with a unique, warm sonic signature all its own. The 013 Tube’s round top end and midrange focus — which is highly musical and never clinical — enable the mic to capture complex, transient-rich instruments and sounds that span the frequency spectrum and dynamic range. For louder sources, the mic’s external power supply is equipped with a 20dB pad. A well-rounded performer in the studio and onstage, the 013 Tube captures every musical detail, subtly enhancing the sound with alluring professional polish.

Custom S13 capsule

Collectively, the engineers at Soyuz have spent decades studying, servicing, and building classic microphones; this unique pool of knowledge, craft, and skill — combined with the golden ears of numerous musicians, producers, and audio engineers — has culminated in the creation of the custom S13 capsule used in the 013 Series. The S13 capsule, with its detailed top end, warm yet present midrange, and controlled low end, possesses the remarkable ability to capture source material with an accuracy that is always smooth, never strident.

Eastern engineering, Western design

The Russian word soyuz means “alliance,” and it signifies the partnership that is the driving force behind Soyuz Microphones. In 2013 American vocalist David Arthur Brown and Russian entrepreneur Pavel Bazdyrev teamed up and launched a company to build world-class microphones in Russia. Soyuz now has 20 full-time employees, and Soyuz microphones are being used by top engineers and producers and have been adopted by artists such as Coldplay, Radiohead, the Lumineers, and Paramore.

What’s in your mic locker?

Among the most cherished assets of any world-class recording studio are its microphones. Take a peek in the mic locker, and you will almost certainly find vintage European tube and FET models made in the 1950s, ’60s, or ’70s. The “human-touch” manufacturing methods and discrete handwired circuitry of that era yielded microphones with sonic characteristics that are distinctly different from modern computer-assisted designs. Soyuz’s original tube microphone designs — while not clones of vintage models — are produced in the old-school way, using manual lathes and drill presses and leveraging the former Soviet Union’s rich technological legacy as a foundation. So what’s in your mic locker? The answer will determine the sound of your recordings.
